New audio/video options
•H.264/HE-AAC codec support:
Flash Player 9 Update 3 includes H.264 video and High Efficiency AAC (HE-AAC) audio codec support that opens up a broad ecosystem and selection of standards-based video — up to HD quality — that developers can leverage in their applications. Supporting a subset of MPEG-4 Part 12 (container) and Part 10 (H.264), including baseline, main and high profiles, Flash Player can play back existing MP4, M4A, MOV, MP4V, 3GP and 3G2 content.
